Study of the relationship between the trace element of oil-gas inclusion and oil-gas movement

The oil gas inclusion in the reservoir is the evident of the oil gas movement. The trace element and its distribution characteristic of oil gas inclusion indicate the feature of the oil gas when it was captured by inclusion. The trace element and its distribution of oil gas inclusion in the different layers of oil well also show the process of the movement and change of the oil gas. Therefore the analysis of trace element of oil gas inclusion can be one of the methods for the trace of the movement of oil gas. In this paper the element contents of about 50 inclusions from the oil field of Zhongyuan, Changqing and Talimu was measured, some results of the relationships between the trace elements and oil gas movement were obtained.
